Thanks all. :P
I did fuse the lame to a lightweight innerfacing. after that it was just like working with any other fabric that doesn't stretch. (at all, so you had better cut it right the first time. :lol: )
The light gray squares aren't lame. They're Platinum Fairy Frost from Michael Miller's line.
I didn't quilt through either one. the back is quilted in the ditch. I attached the top using tiny back stitches, through just the batting, about every half inch in those ditches. for some reason, i just couldn't bring myself to "disturb" the main gray areas with quilting that showed.
the whole thing went through a machine wash and dry like a champ. (what a relief!!! it's tough to hold your breath that long! :lol: )
